| Zusammenfassung: | Distortion-compensation amplification apparatus that can obtain an appropriate error vector magnitude without increasing power consumption and can suppress the distortion of a transmission signal appropriately. A distortion compensation section (13,24,26) applies distortion compensation to the transmission signal. An amplification section (17) amplifies the transmission signal to which distortion compensation has been applied by the distortion compensation section. A frequency component calculation section (27) calculates the power of frequency components of the transmission signal amplified by the amplification section. A peak suppression section (12) suppresses the peak value of the transmission signal input to the distortion compensation section (13,24,26) in accordance with the power of the frequency components calculated by the frequency component calculation section (27). |
